Abstract (en)
[origin: EP2346227A1] Disclosed are a wireless transmission system and a wireless transmission method that prevent CEC protocols from being affected by wireless communication transmission delays or buffering delays and failing when CEC communication is performed wirelessly in the HDMI standard. The CEC control unit of a first wireless communication device (illustrated with a receiver (3)) exchanges CEC messages with the CEC control unit provided for a display device (illustrated with a monitor (4)) using a logical address corresponding to the device type of the AV device (illustrated with STB (1)). The CEC control unit of a second wireless communication device (illustrated with a transmitter (2)) exchanges CEC messages with the CEC control unit provided for STB (1) using a logical address corresponding to the device type of the monitor (4).
